Let me bring some real insider news(don't ask me where I got it and who I am but you will see).

Start 2nd half of next year, N55/N55HP will be replaced by an newer version of N55, power goes up ~10-15% and will start with F32, F10 LCI and F15 X5(Sorry, no F30 sedan), then all cars with N series L6 turbo in the next 2-3 yrs. This will reduce the SKU and hence lower the overall cost.

The next all new N series L6 turbo engine under R&D now is coded N58, displacement very likely stays the same but while its N55 predecessor uses a single twin scroll turbocharger, the N58 is going back with twin-turbochargers again however with one twin scroll turbocharger and the other one not! Power target is 370-400hp range. It's going to hit the market between 2016-2018(2016 the earliest), which is the perfect timing for all new 5/X3 series, F32 LCI, F15 LCI, all new 3 series, etc...

V8 engine will stay pretty much the same, which is the current N63tu, it will replace all N63 next year, though will also get minor tune here and there and goes to 500hp club in the next 3-4 yrs. Currently not sure if displacement will stay the same after 2-3 yrs but as far as technology is not going to be any major changes.

There is also a diesel engine coded N59 under R&D but I am not a fan of diesel so not even want to bother.

OK finally the F82/F82 engine! It's L6 3.2L. Output is between 440-455hp. However starts with MY16 the earliest, it will come with optional power pkg which will raise to 470-480hp in order to give enough gap between the new N58 engine. Though the Power pkg is not just simply increase the boost, it's more about better intercooler liquid and better designed air-to-water system together with upgraded intake/exhaust(so the pkg won't be cheap). F80/F82 engine also has the largest ECU file amount all other BMW models, which is 35MB. The new liquid intercooler holds full 1.5 gallon(or liter, i didn't catch it very clearly) of coolant , and will always keep the air temp below 35C.

Below is what I got from the insider(NOT from any websites or news), but unfortunately is in Chinese. Whoever can read it can clear see how the liquid intercooler is being designed and hopefully someone can translate them all! It's so exciting to read but too professional to translate!!!

Sorry but if that render is from your source then his credibility might be suspect. Look at these recent m3 spy pics. It's clear that the bumper doesn't look like the one on the render from your source.

And where did your source get his info from? Can't just come here posting rumors and not substantiating the validity Though thanks for sharing.

That's not a render according to the insider, it's an early uncovered prototype(of M-Sport?), just look at the side mirrors...He refused to give the most updated info since I already had too much LOL!!!

I agree with you that does look like a render of a standard 3 series by just looking at the fender.

If that's what he told you, then none of his other info that you've reposted can be trusted.

That's nothing but a render of an F30 from the F30 debut event held at the BMW plant in October 2011. Here's the original:
